Description
Technical field
The utility model belongs to fly cutter mixing arrangement technical field, particularly relates to a kind of fibers mixture immersion system.
Background technology
In the manufacturing process of thermoplastic composite, be melt impregnation (dry method) or slurry impregnation (wet method) be all need first fiber opening to be become ultimate fibre, enter next process again, be glass fibre or chemical fibre or cotton fibriia be all pencil, hundreds and thousands of ultimate fibres are had inside mass of fibers, the reason of this bundle fiber bunchy has natural such as linen-cotton, has the artificial such as chemical fibre and glass fibre that manufacture, no matter which kind of fiber, it is tight and dead for combining between ultimate fibre and ultimate fibre, has External Force Acting just can open.
Now conventional colter mixer makes bundle fiber break up and adds solid particle to mix, but colter mixer only has following both sides fly cutter to break up the bundle fiber that colter is dug, fly cutter negligible amounts, every mass of fibers bundle is made to touch the probability of fly cutter relatively also less, and the fly cutter direction of motion is separately a kind of vertical and barrel wall, the effect played for the fibre bundle being parallel to barrel wall is very little, can not effectively break up fibre bundle, so need the mixer of better effects if to replace colter mixer.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of fibers mixture immersion system, adopts multi-faceted fly cutter to arrange, the fiber by digging can be hit by omnibearing fly cutter, ensure that fibre bundle is fully broken up and fully mixes with solid particle.
The utility model solves the technical scheme that its technical problem adopts: the immersion system provided comprises urceolus, fly cutter assembly and shaft, the middle part lateral arrangement of described urceolus has shaft, described shaft is evenly arranged several blade groups, each blade group is made up of the blade that stretches out be evenly arranged along shaft periphery, each madial wall stretching out blade and urceolus is close to, and the medial surface of described urceolus is furnished with and inwardly stretches out fly cutter assembly.
One as immersion system described in the utility model is supplemented, install in the space of every cubic metre, the inside of described urceolus and be no less than 2 fly cutter assemblies, the central shaft of this fly cutter assembly is vertical with the madial wall of urceolus or arrange in 45 ° of angles, the central shaft length of each fly cutter assembly is no less than 1/5 of outer barrel diameter, in order to can fully hit fiber in different positions.
One as immersion system described in the utility model is preferred, evenly distributed in the rotating shaft of described fly cutter assembly have the some groups of fly cuttves be evenly arranged along shaft circumference face, the quantity often organizing fly cutter is no less than 2, the length of the fly cutter of different group is inconsistent, the shape that the two ends often organizing the projection of fly cutter on each fly cutter assembly connect into is trapezoidal or dolioform, often the length of fly cutter is all no more than 30cm, the fly cutter of different length makes fly cutter can hit the fiber of diverse location.
Another kind as immersion system described in the utility model is preferred, the described central axis stretching out blade and shaft or arrange in 30 ° ~ 60 ° angles, and in like manner, be also to make the rotation of fly cutter assembly increase, strike is more increased to the probability of fiber.
One as immersion system described in the utility model is supplemented, and the circumference cut surface often organizing fly cutter composition on described fly cutter assembly is vertical with rotating shaft or arrange in 30 ° ~ 60 ° angles.
Described fly cutter assembly is driven by the motor be arranged on outside urceolus, and motor can be servomotor, is convenient to control the rotating speed of fly cutter assembly.
The upper end of described urceolus is furnished with circular arc valve, and this circular arc valve is manually opened or pneumatic unlatching, and this circular arc valve embeds urceolus and also flushes with outer tube inner wall, prevents outside the fiber in urceolus from dispersing.
The quantity adding fly cutter arranged by the multipoint fly cutter of multi-angle, increase the probability of fly cutter and fiber bundles contact, and in the selection of rotating speed, fly cutter rotating speed is more than 20 times of agitator shaft speed, fiber fully can be hit by fly cutter to have this speed difference just can ensure.
Present patent application makes full use of convection current mixing principle, namely utilizes the upthrow motion of material in mixing arrangement to form fluidized bed, produces instantaneous weight loss, make it to reach best admixture.In fluidized bed field, material overcomes centrifugal force with certain peripheral speed, and material, under specific overlapped blades effect, moves axially, and realizes mixing in comprehensive scope, forms random optimal movement state.In the mixing chamber with certain peripheral speed, form fluidized bed, the material in layer mixes under the effect of convection current mixing principle, and is being in state of weightlessness instantaneously, thus obtains a homogeneous mixture.
The principle of fiber dispersion is that the strength of more than 2 different directions acts on fibre bundle, fibre bundle is loosened and is opened into ultimate fibre, this strength or can be described as shearing force, these are sheared, and the speed of strength is faster, strength is larger, the words of same speed, distance is far away, strength is larger, and constantly repeat shearing force and be applied to fibre bundle, fibre bundle is just cut into ultimate fibre.
In the setting and selection of blade, the angle of paddle determines to stir direction, and must meet 1 condition, be exactly will material toward fly cutter upthrow.Conventional has paddle blade structure preferably flat, because flat blade turning over materials is shed toward both sides, the distance that fly cutter shed by material is moderate, and two kinds of object proximity speed is also than comparatively fast, and impact the shearing force produced enough large, fiber dispersion effectiveness comparison is good.
In addition, paddle size determine shed material number, paddle width design covers barrel as far as possible, the material that such leakage is turned over is few, mixing is also even, Blade height is higher than the height of fly cutter group, and design creates to fly cutter the space that rapidly impacts material like this, do not allow material stop near fly cutter, because from fly cutter more close to, dispersion effect is poorer.
When carrying out mixing, the length of corresponding fiber is the longest can 25mm, is longlyer just difficult to realization and fully breaks up, and the solid particle simultaneously added can be 10-40 object size, without the need to too small particle, and wherein preferred 30 object sizes.
So paddle at an angle rotate make fiber and powder in cylindrical shell radially, the upset of axis, hoop combined-circulation flowing and shedding, the fly cutter simultaneously installing the High Rotation Speed of surrounding makes fiber and powder impact rapidly again and again and produces shearing force by fibre bundle and disperse, and fiber and powder produce the positive and negative charge that attracts each other and be adhering to each other together because material polarity is different, realize fully mixing of polymeric matrix powder and fiber.
